Hope that helps! ]]> https://www.displayfusion.com/Discussions/View/rdp-only-allow-2-of-3-monitors-to-be-used/?ID=424b5d21-52c6-46bb-baf4-5ab8fbc8ee51 Tue, 21 Feb 2017 15:50:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/rdp-only-allow-2-of-3-monitors-to-be-used/?ID=424b5d21-52c6-46bb-baf4-5ab8fbc8ee51 DisplayFusion Hi Everyone,

I purchased a Pro license just to test out something working but it doesn't appear to.

I have 3 monitors

1) Dell U2715H
2) Dell U2715H
3) Dell U2715H

All at 2560 x 1440.

Gfx Card: Intel HD Graphcs P530

I've tried following this guide: https://www.displayfusion.com/Discussions/View/splitting-a-spanned-remote-desktop-rdp-session/?ID=5b1675da-85f6-4994-9255-d453b2c78ff3

But adapting it slightly as I have 3 and not 2 monitors. I do think I got this to work, but the RDP window still spanned across my 3 monitors and didn't do as I thought/hoped it would do and give me back the 3rd monitor to the host machine (outside of RDP).

I'm remoting into a Virtual Machine running in Hyper V on the same computer.

I've tried disabling the 3rd monitor within DisplayFusion but I get the following error:

An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 5]

I wonder if this is because I'm in an RDP session, as I know you can't adjust display settings nativity while in RDP via Windows control panel either.

Any help or other suggestions to do what I need would be greatly appreciated.

Thanks,

Michael ]]>
